what is the shank size?

Not sure but it will fit in any standard 3/8 drill (about the size of a #2 pencil) You probably have one in the garage lol.

Can these bits drill holes in both ceramic and more so porcelain tiles successfully???

I can't speak for the porcelain tiles, but I've used the bits for ceramic, glass, and a composite stone kitchen sink. Worked like a champ.

Want to drill granite countertop that is 1 1/4 inches thick. The specs for this bit say it will drill 1" deep. How do I drill to the depth needed?

I don't think these drills will work, unless you can find some way to drill the last 1/4 from the other side and make the holes match. The drills have a habit of sliding until the hole is started. I drilled a same/size hole in a piece of wood and placed the wood hole where I wanted to drill. The wood held the bit in place until I got the hole started.

looking to see if these will cut good holes in glass blocks

I used them to drill holes in Patron Bottles worked really well for that. Don't know how thick your glass blocks are but they are quality bits I would give them a try if it was me! I would put a piece of paper tape on area to be drilled to keep it from chipping and keep the glass wet! You should be fine.
