Can my 7 mnth old eat foods if nt pureed?

I have been feeding him solids (fruits and veggies) for 1.5 months. I puree everything (like baby food jars) using a blender. Can he now eat foods which are only mashed and a bit lumpy? I am so paraniod annd worry a lot. Also I boil the apples and pears. Do I still have to boil them? thxxx for all the help :)
