Check on fossil ID Reptile/dino teeth?

[fossil35]

I wanted to check on 2 fossils IDs before I tried to label them. They are from Wyoming. From Lance formation.

 

 

#1 (was thinking theropoda) (serrated part seems bigger on one side and smaller on other)

 

 

#2 (other side)

 

 

The next tooth was thinking to be croc tooth.

 

#3(very little)

 

#4(closer view)

 

#5(different angle)

I agree with that id on  the croc tooth, but I am not sure on the first one. @FB003

I think I'd be comfortable with ind. theropod. I can't really help with ID at that size.

Thank you for the help.
