Suppose that I have a 5 qubit quantum computer and want to generate
- 4 entangled states (each of 5 qubits)
- Single 6 qubit entangled state.
Are these 2 cases possible? I am a beginner please help!

To go straight to your questions:
One way I can think of creating a 5-qubit entangled state is to have one qubit in superposition with a Hadamard gate and then a CNOT from that qubit to the other four qubits. If you wanted 4 of those 5-qubit entangled states, then you'd just repeat that for the other 15 qubits in groups of 5. Here's an example in the circuit composer from IBM's Quantum Experience:
