For a see-saw shape (AX4E), would the angles be <90?

Yes, the angles would be less than 120 and less than 90 because the lone pairs causes a slight electron repulsion.

The lone pair causes the angle to be slightly less than 90 degrees.

Yes if asked for one bond angle then you can either say it is slightly less than 90 degrees or slightly less than 120 degrees. The reason for this is because the one lone pair causes electron repulsion than push the atoms closer together because the atoms want to minimize the electron repulsion experienced by the lone pair.
