Do I have to add lining under the soil to an edging on a paved surface? I want to create an edging along my side passage and I was wondering if I need to add any sort of lining (plastic?) before I lay down the soil?
I would use a lining or protective barrier up against your foundation.
I would certainly check with your local home improvement store for the proper materials for this application.
I have a piece of land that I have prepared for the next job. I want to put flags down but I also want to use some leftover decorative small pebbles. What I need to know is how wide in between the slabs should I make it and how do I work out how many slabs I will need? The size of the plot is 4.5 meters in length and 2.5 meters width. This plot, when done, will serve as a games area and seating area. To the left of this plot, I have built a fish pond with waterfall and in between the plot of land and the fish pond will be a walkway of sparkly white pebbles that shine when it's dark.
Sounds like an amazing project.
I would consult with the quarry that you are purchasing your material from as to the amount of material you will need to purchase for your project.
I want to know about the space requirements for human planting something on the garden. Could you tell me please? Thank you so much. :)

Am building a container veggie garden (on legs, waist high) out of logs and wonder should it be lined with plastic liner with drainage holes cut to keep it from drying out quickly and help with cold or would there be a concern about toxic substances leaching from it? Also, will a 'lasagna' technique work in this?
You don't need the plastic to keep it from drying out. In raised beds like that, most people use it to help prevent damage to the wood of the planter from the wet soil. I personally do not have any concerns about there being toxic chemicals from the plastic, but I do know people who have concerns about using less than food grade plastic for food growing projects. For this, it is a personal choice.
A lasagna technique works well in these kinds of raised beds.
Which plants go from center outwards in keyhole garden?
The beauty of keyhole gardens are you that you can design and plant them to your needs and liking.
I personally would plant the tallest plants in the center and work out from tallest to the shortest plants on the outer edges.

I built a retaining wall 3 ft high X 25 ft wide at the base of an area slanting down to the wall. In the yard are a lot of stones and rocks that I would like to use for fill before putting dirt in the deeper area. Will that work for growing? Will the rocks draw and become a habitat for snakes? I live in the SE US.
It sounds like you have essentially created a kind of rock garden and there are a wonderful number of plants that do well in this kind of garden. This article can help get you started:

Yes, this type of structure in the garden will attract snakes. But this is not a bad thing. Most snakes are benign if left alone and can do a wonderful job of keeping out unwanted pests from the garden.
Do you have pictures of edging the garden with old plates? I have searched for hours and can't find any. I will so appreciate any you can send me.
