I have a purple potted clematis with some English ivy. The problem is I have noticed some new different leaves which don't look like the clematis leaves or the ivy leaves. These leaves have tiny unopened lilac flowers at the end. Are these weeds? Because I bought this potted clematis, I don't know if it has something else in it as well. The new leaves, which I think are weeds, are growing quickly but their tiny flowers are few and unopened. Please help. Thank you for your time.
I can not tell what it is from this description.
If it came from a nursery it certainly could have been seeded with another plant.
If the clematis has reached, say the top of the fence, can I nip out the lead shoots?
Depending on the type of Clematis you growing there are specific pruning needs.

I have a clematis and small hydrangea. They are each in a large container on my patio and cannot be moved. The problem is my patio has a roof over it so they do not receive any rain but I water them regularly and they are doing great. I was wondering what to do in the winter time. Should I water them once in awhile or stop watering if it is freezing? I don't want to kill them but I do not know how to water in the winter. I hope you can help me.
Yes, you will need to provide water until the plants go dormant.
Here are a couple of articles.

I have a Pink Champagne and a Nelly Moser clematis, planted 7 years ago. They have a trellis supported by a fence. For several years they flowered beautifully, but the last two years they exploded with vine growth, so heavy it grew in mats and this strangled out most of the flower buds. The only thing I did different was give them a large topping of homemade compost in April. No chemical fertilizer. What can I do to calm down their growth? Thank you.
Bone meal added to the soil should help with the blooms. As for keeping the vine in check, it may be necessary to prune. This article should help: https://www.gardeningknowhow.com/ornamental/vines/clematis/growing-clematis.htm
I am having my house painted and I have three large clematis that run up the side of the house. They are going to have to come down. Will it hurt to cut them this early in the season? Any other suggestions?
Hold off pruning until early spring for most types or following bloom in others. While it should not hurt the vine, depending on the type you have, blooming may be delayed or skipped entirely the following season if cut back too early. It may just be in need of some fertilizing too, which should help give the plant a jump start with growing.
I planted my Clematis about 2 months (or more) ago and it has not grown even 1 new leaf, even though it looks very healthy. It did have a couple of flowers and 1 bud which flowered. I believe that the rootball might still be intact even though I loosened it before planting. Should I wait and dig it up this fall, loosen the roots, add more soil and replant? Or is there something else wrong and what should I do? Thank you.
As long as it looks healthy and it's planted in an adequate location with well-draining soil, I would not dig it back up. The roots need time to become established and this will only cause the plant more stress. You may instead try giving the plant some fertilizer to boost its growth. Use a fertilizer high in phosphorous on your clematis. Something that is about a 10-20-10 NPK ratio or even rose food can be used to fertilize clematis. Anything having too much nitrogen will only result in an abundance of foliage growth with few blooms.

This is only the 2nd year I've had it but last year it bloomed all summer. This year I had a lot of blooms at the beginning of the summer but then nothing. Why isn't it continuing to bloom? Thanks.
A lack of phosphorus, which is responsible for blooming in plants, could be the issue. If your plant is lacking phosphorus, use a phosphorus rich fertilizer or add some bone meal to the soil.
