hi..all my renders are 72 of resolution, they look really pixelated, how can I have the jpg files at 300 ?

On the Windows system, you cannot adjust dpi settings. But that is not even necessary. Say you need a 30 cm wide image at 300 dpi. 300 dpi is 300 dots per inch which is ~118.11 dots per cm.

That is 30 x 118.11 ≈ 3543 pixels.

So if you do what Kris suggested and calculate your export settings as per above, you get the same image size. dpi settings are only for printers to know how "densely" they should print. On screen, it has no meaning at all. Most image editing applications can then set your dpi (which is then "embedded" as info into the image for printers)

An extra tip: SU makes a bit crappy antialiasing. So if you need the above image with really nice and crisp lines (vs. jaggy ones), export at a double resolution ( ~7086 pixels) and then resize your image in an external editor (where usually at the same time you can set dpi settings in the same dialog) to half of the original export, using some better antialiasing algorithm.

You need to learn some basics... learn to walk before you run...

The illustrated things could be images [inside a component] or faces with a textured image applied via a material.

Use Entity Info to show what kind of thing it is that you currently have selected...
Edit the 'container' component - by double-click.

Let's deal with them in turn...

Image: select it and right-click context-menu 'Export'.
This lets you save the Image as an external file with the same name...

Material: select a face using the material.
Open the Material Browser dialog.
Open its Model-tab [little house icon].
Select the material.
Select the Edit-tab.
That will show the material's image file near the bottom of the dialog.
There's an icon to the right of it's name, to allow you to edit the texture's image file.***
Once you have opened it you can do a Save_As in another format or location if needed...

***Note you must have an Default-Image-Editor set in your Sketchup Preferences dialog's 'Applications' tab - typically this will be Gimp or Photoshop... Do that before editing the texture, so it exports and then opens for you...

Edit the PNG image as described before to make the background transparent...
Use that edited image-file as a replacement Image under Import... or as a replacement texture-image file under the material's Edit...

Hi Oscar, hi folks.

For your problem number 1, for a face to closes it must meet these requirements:

there must be no gaps between edges;

there must be no edges protruding inside the face;

all endpoints must be coplanar;

no edge shall be smaller than about 1/16 inch or 1 mm (approx).

If you can post the model, or at least the problematic part, someone may be able to show you where is the problem or where are the problems.

Just ideas.
