The question didn't ask about tantalum vs.electrolytic capacitors, so removed that from the title. Also made the title fit the actual question better.

Ceramic capacitors in parallel and Tantalum vs. ElectrolytIs this configuration suitable?

I am building a circuit based on an Atmega 328PATmega328P. In the schematic of the datasheet are 3 capacitors (1uF, 4.7uF polarized, 1uF) in parallel to each other on the power supply Vcc. I assume these are for decoupling purpose.

I currently only have 470nF ceramic film capacitors (805) and tantalum capacitors (805). Is it possible to connect 2x470nF in parallel to achieve the ~1uF on the respective lines? In theory the capacitance is 940nF, but since it is used for decoupling it might be bad for the signal since, because I solder two parts instead of one (more solder, cables, cable length,more more resistance,  ...).

Does this matter in a practical situation?

EDIT: I build the circuit on a hole grid breadboard
