This is the month of June and my grape hyacinths have bloomed and are now yellow and the flower buds are still upright. Can I cut the leaves and flower buds?
Yes, you can cut their leaves and buds. Once they go yellow, they are dead and no longer help the plant.
I have mums and grape hyacinths. They have both wintered in my kitchen. How do I restart them? Can I use the flowers from the mums to plant and start them growing again? My grape hyacinth has passed the bloom stage, now what do I do with them?
If the mum plant is still green, you should just be able to set it in a sunny place and it will sprout and grow. You can also take cuttings. Here is information on that:

As for the grape hyacinth, leave those until the leaves yellow. Once the leaves are yellow, you can store them until next year. Here is information on how to do that:

In addition, you will need to put them in the fridge for 6-8 weeks to chill them in order to get them to bloom next year.
How do I store grape hyacinth until the fall?
Store your bulbs in a cool, dry, area. Or you can go ahead and plant them now, they will bloom in the spring

I purchased grape hyacinth bulbs through mail that are already sprouting. I had hoped to store some over winter and force some indoors. Just received in mail and they all have one to five inches of growth. What do I do with them? Can I still store or force or do I need to plant them now? If planting is necessary, will they bloom?

Can I transplant grape hyacinths after their foliage has come up in October?
Yes, you can transplant them just about any time, depending on your location. Grape hyacinths are quite hardy and take tranplanting well as long as you provide the proper growing conditions and care.

I never planted them, but I now have an extensive crop of grape hyacinths. I don't mind, however, in one of the gardens, they grow long and limp leaves that lie down in a tangle. I gave them a trim, but I'd rather have them stand up by themselves. I'm guessing some lack in my soil, but I don't know what it might be.

Everything I read says that Grape Hyacinths need to be planted in the fall. I just purchased three large pots of grape hyacinths that are currently in bloom. Is it ok to plant them in the ground now even though it is springtime, and how deep do I plant them since they are plants, not bulbs.
Planting is usually performed in fall for spring blooming plants. That does not mean you can't go ahead and plant them now, only that you may not see any blooms until the next season.
You may want to wait until the blooming has finished before planting them out. Plant them at the same depth as the container they are currently in. Here is an article that you may find helpful: https://www.gardeningknowhow.com/ornamental/bulbs/grape-hyacinth/planting-and-care-of-grape-hyacinths.htm
