You'd be better off with a resistor for each LED. This is good practice because not all LEDs are created equal. Their exact forward voltage drop varies slightly, causing the current and brightness to be uneven between each LED, affecting lifespan. Resistors are cheap compared to LEDs so I'd say this is usually a good idea money-wise to include them.

You can see this by changing the voltage value of some of your LEDs in your design, change one from 2V to 1.92V and it will sink most of the current and burst in the simulation. Look up my profile, there's an example explaining this.
