It depends on what games you are playing, and what way you prefer to play. For example, playing at a 6-max table would mean you can have a higher VPIP because the field is smaller. And if your table is tight, you can have a higher PFR because you get good value out of stealing blinds etc.

Generally speaking, a VPIP above 30% would be heading towards loose play. And a PFR above 20% would mean you are raising quite often (ie, 1/5th of your hands are raising hands).

Aggression factor would be down to your style of play, whether you like to be aggressive with draws etc.
