3. There are some books on the shelf on the wall.
(Are they grammatical? Would you check them? Thank you.)

Answer 1

These are perfect grammatically correct sentences, dude. :D

Answer 2

herp is right. These are really good. One thing, though:

In #1, use either "is" or "lies" (not "lays"). It's that tricky pair of verbs that many English speakers don't get!
