Three is the answer expected. Higher valences of phosphorus, in PCl5 for example can be explained by hybridisation although this method is not the only explanation.
wo. A strange question! if you hybridise the 3s and 3 p orbitals you end up with sp3 and still get the same answer. Perhaps the hybridisation involves d orbitals, if that is what you are being taught.
Calcium can form the ion Ca2+ and forms many ionic compounds. Hybridisation would indicate we were talking about covalent bonding, calcium is not good at this, for example organo-calcium compounds are much more unstable than magnesium.

Without hybridization, oxygen has a valence electron configuration of 2s22p4. Which means it has 2 unpaired electrons; therefore it can form 2 bonds.

Its all because of the electron dencity around the nucleus.when a carbon atom makes 3 bonds with another carbon atom there exists 1 sigma bond and 2 pi bonds,but it needs very high energy to have 1 sigma bond and 3 pi bonds that's why a carbon atom cannot make 4 bonds with another carbon atom.
The hybridization of Titanium in TiCl4 is Sd3 covalant Liqiid with boilling point 136 degree centigrade. The 4S2 electron is promoted to 3d orbital to make it d3 followed by Sd3 tetrahedral hybridization.
An atom can make a number of covalent bonds equal to the number of electrons it needs to fill its outer shell
Electrons.
A carbon atom can form 4 single covalent bonds
Covalent bonds between carbon atoms; simple, double or triple.
