Having a best friend is being able to share in those things you both enjoy doing together. They are the ones who you would turn to for any help or advice you may need. They are a good companion to share part of your life with.
You are quite right in saying the relationship difference is physical. Hopefully the close bond you share with your lover will be within the bounds of marriage. It is private and something to be cherished between you both. There is always that best friend relationship which exists between lovers, and though best friend relationships can and often do contain love, it is only platonic.(Free from physical desire).
How they introduce them. Friend: "This is my friend, so and so" Lover: "This is my, um, friend, so and so"
A friend can be a lover and a lover can be 'just' friends! Sexual intercourse is involved with a lover, mental and emotional intercourse are more the realm of a friend. Hence, the categories need not be mutually exclusive!
A boyfriend is a romantically favored male. This can be someone you are dating, or just hanging out with. There does not have to be any physical intimacy (sex) involved. A lover is someone that you are intimately involved with. You can have a boyfriend without him being your lover, but it is assumed that if you have a lover he is your exclusive boyfriend.
Paramore is a band, fronted by Hayley Williams. The name derives from a friend's mom's maiden name. Paramour means "secret lover".

Betrothed is a word that means engaged to be married. A lover is someone who you have a romantic relationship with. You can also say that someone is your lover and that you are betrothed to them though.
ALWAYS AS A LOVE, WHAT WILL MEANS A FRIEND FIRST AND A LOVER LATER
For a guy a 'girlfriend' is someone he is serious about and is in a committed relationship and may or may not include a physical relationship depending on age of people etc. A 'lover' is generally not a committed relationship and is just a more elegant way of staying 'FWB' or 'F**k Buddy'!
