Make larger capacitance using multiple capacitors?
Yes. The formula for capacitors in parallel is

$$ C_{Total} = C_1+C_2 + C_3 + ... $$

Make sure that each one is rated for at least the voltage you will apply to them.

For reference, capacitors in series are calculated as follows:

$$ \frac {1}{C_{Total}} = \frac {1}{C_1} + \frac {1}{C_2} + \frac {1}{C_3} + ... $$
