how many times should I feed my 8 months old baby boy in a day, and what else can I feed him besides pureed fruits and veggies?

Besides fruits and vegetables, you can introduce meats (ground meat), pasta (softened and mashed) and dairy such as yogurt and cheeses (no soft cheeses and make sure baby is not allergic). Most babies at this age usually eat 3 “meals” per day at this stage. A balanced diet would include a type of grain, fruits, vegetables and a protein source. That being said, baby's appetite may change daily (if he is distracted or sick) so keep a lookout for that and adjust accordingly
